Line lengths are inaccurate
If you have measured your printed lines and nd that the lengths are not suiciently accurate for your purposes,
you can try to improve line length accuracy in the following ways:
1. Print on HP Matte Film, for which your printer's line length accuracy is specied. See Functional
specications on page 172.
Polyester lm is about ten times more dimensionally stable than paper. However, using lm that is thinner
or thicker than HP Matte Film will reduce line length accuracy.
2. Set the Print Quality slider to Quality.
3. Maintain the room at a steady temperature between 10 and 30°C (50 and 86°F).
4. Load the roll of lm and let it rest for ve minutes before printing.
5. If you are still not satised, try recalibrating the paper advance. See Recalibrate the paper advance
on page 139.
Image Diagnostics Print
The Image Diagnostics Print consists of patterns designed to highlight printhead reliability problems. It helps you
to check the performance of the printheads that are currently installed in your printer, and whether any printhead
suers from clogging or other problems.
To print the Image Diagnostics Print:
1. Use the same paper type that you were using when you detected a problem.
2. Check that the selected paper type is the same as the paper type loaded into the printer. See View
information about the paper on page 33.
3.
At the printer's front panel, tap , then , then Print diagnostic image.
It takes about two minutes to print the Image Diagnostics Print.
The print is divided into two parts, both of which test printhead performance:
Part 1 (top) consists of rectangles of pure colors, one for each printhead. This part represents the print
quality that you will get from each color.
Part 2 (bottom) consists of small dashes, one for each nozzle on each printhead. This part complements
the rst, and aims more specically to detect how many faulty nozzles each printhead has.
Look carefully at the print. The names of the colors are shown above the rectangles and in the center of the
patterns of dashes.
